Saunders Industrial Diaphragm Valves

The Saunders® Industrial Diaphragm Valves, first developed more than seventy years ago, have evolved to handle more fluids, gases, solids, and powder than any other type of valve. A wide choice of materials are available and a flexible range of operating methods have been developed to satisfy the needs of most industrial applications.

Extended life, reliability, safety and ease of use, combined with an essentially simple design, facilitate low maintenance and minimal running costs

Features

When subjected to both pressure and vacuum, Saunders® industrial diaphragm valves operate and close 100% leak-tight. This feature reduces processing and handling costs by cutting out the waste normally associated with conventional valve designs.

Available in both weir and straight through designs and with a number of lining options to suit both aggressive and abrasive line service

When manual operation is inadequate or inconvenient, Saunders offer a variety of actuators covering valve sizes up to DN250, for different line and operating pressure options. We offer three different actuators, designed for various characteristic performances.

Benefits

  • Corrosion resistance
  • Abrasion resistance
  • Leak tight* – on pressure and vacuum services, valves operate and close *100% leak tight in accordance with standards MSS SP-88 and BS EN 12266-1, even after thousands of operations, reducing processing and handling costs, by eliminating emissions normally associated with other valve designs.
  • Easy maintenance
  • Operating mechanism no in contact with line media
  • Suitable for control – Throttling and control characteristics are enhanced by a streamlined flow path that is cavity free and provides excellent flow control capabilities.
  • Cost effective
  • Valve usable in any position self drain – The Saunders valve can be installed in any position without affecting its operation. However, we recommend installation to be at least 6 times the pipe diameter from bend or pump (10 times the pipe diameter if the valve is used for control).
